This is something i've found on-line
"Part P of the Building Regulations covers installations intended to operate at LV or ELV. These are:
- In a dwelling (houses or flats);
- Dwellings and business premises with a common supply (eg: shops or pubs with a flat above);
- Common access areas in blocks of flats (corridors & staircases);
- Shared amenities in blocks of flats (gymnasiums and laundries, but excluding lift power supplies):
- In or on land associated with the buildings (eg: fixed garden lighting and pond pumps); in outbuildings such as sheds, detached garages and greenhouses.
Therefore, electrical contractors and installers working on outdoor installations, including outdoor wiring accessory installation, should be ‘Competent Persons’, and should therefore be well versed in all aspects of outdoor electrical installation practise, especially if they are involved with it."

- [FONT=Arial, sans-serif]extensions to circuits which are associated with special locations, such as bathrooms. This would include electrical installation work carried out in a bedroom containing a shower (Regulation 601-08-02 of BS 7671 refers). This is what is being referred to in the Voltimum newsletter which you quote. [/FONT]
- [FONT=Arial, sans-serif]extensions to circuits associated with special installations, such as gardens. [/FONT]
[FONT=Arial, sans-serif]Note f further states that work in detached garages and sheds is notifiable only if it involves new outdoor wiring. As indicated in the Napit checklist, this applies also to greenhouses.[/FONT]
